This patch reduces latency in the OpenSL ES player path by calling the
callback immediately before data is consumed, rather than after.

The gperf behavior for using length seems to have changed since
last time this was built, despite being the same version number.

  Revert "For checkbuild, disable all Wilhelm tests in 64-bit"

* commit 'e773894b':
  Revert "Only build libwilhelm, libOpenSLES, libOpenMAXAL in 32-bit"

This reverts commit 4a762c2b.

This reverts commit c6d1318d.

* commit '297ca210':
  For checkbuild, disable all Wilhelm tests in 64-bit

These depend on libOpenSLES.so or libOpenMAXAL.so,
which in turn depend on libstagefright.so, which is not 64-bit ready yet.

* commit 'dde6053e':
  Only build libwilhelm, libOpenSLES, libOpenMAXAL in 32-bit

This change is temporary: native audio APIs must be available to 64-bit
apps, so this will need to be reverted.  However currently the dependent
libraries needed here are not available in 64-bit.

* commit '5c057d44':
  Remove use of pthread_mutex_lock_timeout_np.

Replace it with the portable pthread_mutex_timedlock.

This fixes the 64 bit build, because pthread_mutex_timedlock
isn't defined for LP64.
